Abstract: When a process of returning a vehicle is performed, a fee setting device identifies a zone where the vehicle is returned, and calculates the identified zone's zone SOC. The fee setting device determines whether a discount for leveling is applicable. The fee setting device compares a zone SOC of a zone where a user rented a vehicle and a zone SOC of a zone where the user returned the vehicle. When the zone SOC of the zone where the user rented the vehicle is larger than the zone SOC of the zone where the user returned the vehicle, the discount for leveling is applied.

Abstract: When a user who utilizes a gasoline-powered vehicle shifts to EV car sharing, and the user wishes to have applied a discount for shifting to EV car sharing, a fee setting device setting a car sharing fee requests the user to input a cost paid in the past to purchase gasoline. The fee setting device registers the cost paid to purchase gasoline, as input, and if the cost paid to purchase gasoline is a predetermined amount or more, the fee setting device selects a first discount and sets a basic fee. If the cost paid to purchase gasoline is less than the predetermined amount, the fee setting device selects a second discount and sets a basic fee.
